Recrystallization of Forged 0Cr19Ni9N Stainless Steel

The specimens were taken from forged 0Cr19Ni9N stainless steel which was industrially produced. Recrystallization of the steel was investigated. The results have shown that fine and uniform microstructure can be obtained from original coarse grain size through recrystallization.The higher the stored energy by deformation, the lower the recrystallization temperature. The finer the original grain size, the lower the recrystallization temperature. Increasing recrystallization temperature can greatly enhance the process of recrystallization and result in decreasing strength and increasing ductility.
